TO'ALL WHOM I'l MAY CONCERN:

Be it known that we, WILLIAM HARRIS and CLINTON BROWNING, of Rush. Run,Jeerson county, State of Ohio, have invented a new andusefulimproveinent for preventing the rattling of Nuts, and forpreventing them from becomingv loose; and we do hereby declare thefollowing to be a full, clear, and exact description thereof, suiicientto enable any person skilled in the nrt to make and practise ourinvention, reference being had to the accompanying drawings, forming apart o f this, our specification, in'which- Figure lis a perspectiveview of our improvementv applied to an ordinary nut which has beenscrewed upon a bolt.

Figure 2, a cross-section of fig. l; and

Figure 3, a view of our improvement detached from a. nut.

The object of our invention is to provide the means whereby, withcertainty and ease, and with only a moments work, aretaining device maybe added to a nut of ordinary construction, which shall eiiiciently holdit in place Where it has been applied for use, and also prevent it frombecoming looseand rattling; and which invention is also equallyapplicable to hold in pla-ce a pin, such as is used in hinges o1'`joints. i

For these purposes we construct a spring friction yoke, a,\of metal,having aspring temper, in the form represented in the figures; whichyoke a is provided with a female screw,.b, that may precisely registerwith the male screw c `of`the bolt to which .it is intended to beapplied. .But forv this purpose it is not intended that the diameter ofthe yoke a should'be the same as that of the bolt, but thejsize of thescrew-thread oniy; and that, of the female screw should be the lsalue,or nenrly the same. IThe yoke itself, however, should be c onstructed ofa diameter; (in that part of it which is intended to clasp the bolt)less than the bolt, so that When applied tothe bolt, as shown in figs. 1andv 2', the bolt b will he firmly clasped with a constant springfriction `suicient to retain the hold ofthe yoke upon the bolt `and thenut c to its seat. 'For convenience in applying thc yoke to the bolt, weconstruct it with projections :1: x, so that when a pocket wnench,such', for instance, as seen in Figure 4, is applied between saidprojections, they may readily be spread apart, and thus the -yoke beeasily turned upon the bolt, whether it, be for the purpose of screwingup or unscrewing Hoving thus described our invention, what we claim asnew, and desire to secure by lLetters Patent of the United States,` is-We claim, as an article oi:.manufacture, a. spring-metal friction yoke,constructed 'substantiallyin the manner and for the purpose herein s etforth. Y v

WILLIAM HARRIS, CLINTON BROWNING.'
